Known Issues - Red5 Pro Server


  • Shared objects testbed example does not support the special characters " and \
  • Some quality issues are observed if subscribing to high-definition streams with the mobile SDK on Android and enabling hardware acceleration.
  • With server >= 8.0.0, for localhost testing, it may be necessary to set force.local.ip= to your machine's IP address in conf/webrtc-plugin.properties
  • For server version >= 9.0.0, if you need the Orientation post-processor feature, contact us at info@red5pro.com to help get you a compatible FFmpeg library.
  • If using the Orientation Post Processor, note that the Android SDK recordings take approximately 3 times the duration of the file to convert to MP4; modify the cloudstorage-plugin.properties file, setting the max.transcode.minutes= value to allow for this timing
  • IMPORTANT: Because of different libcrypto library versions supported between CentOS and Ubuntu, if you are using CentOS it is necessary to modify {red5pro}/conf/webrtc-plugin.properties, and change openssl.enabled=true to openssl.enabled=false
